This test is poorly organized in several ways, one of which is that the tests are redundant. When you test whether quantity is greater than 1000, you don t also need to test whether it s greater than 100 and greater than 10. Consequently, you can reorganize the code:

The main difference between this code and the previous code is that the expressions in the else-if clauses don t rely on previous tests. This code doesn t need the else clauses to work, and the tests actually could be performed in any order. The code could consist of four ifs and no elses. The only reason the else version is preferable is that it avoids repeating tests unnecessarily.
Convert a nested if to a case statement You can recode some kinds of tests, particularly those with integers, to use a case statement rather than chains of ifs and elses. You can t use this technique in some languages, but it s a powerful technique for those in which you can. Here s how to recode the example in Visual Basic:
Visual Basic Example of Converting a Nested if to a case Statement
Select Case quantity Case 0 To 10 discount = 0.0 Case 11 To 100 discount = 0.025 Case 101 To 1000 discount = 0.05 Case Else discount = 0.10 End Select
This example reads like a book. When you compare it to the two examples of multiple indentations a few pages earlier, it seems like a particularly clean solution.
Factor deeply nested code into its own routine If deep nesting occurs inside a loop, you can often improve the situation by putting the inside of the loop into its own routine. This is especially effective if the nesting is a result of both conditionals and iterations. Leave the if-then-else branches in the main loop to show the decision branching, and then move the statements within the branches to their own routines. Here s an example of code that needs to be improved by such a modification:
